 AFAIR, the only problem was that the old sec-Device name was abused. I
 do not see a problem in just adding a cam or whatever device in dvb-
 core and use that.
 Or just rename sec since it is no longer used.

Dear all,

I'm looking for a while the work done on the nGene driver and especially the
CI driver.
For sure, this new kind of card add a lot of flexibility as the CI is
completely independent.

I wondering if a parameter can be added to the driver in order to make the
card working like a classic one:

- Having the tuner#1 working with the CAM the classic way:

  * Keep the frontend0 device as it is for controlling the tuning parameters

  * Create the ca0 and sec0 devices attached to the CI like it is done now

  * Send the full TS stream from the demodulator unfiltered to the CI
interface (CAM usually need full TS stream for working correctly - The Multi
Transponder Decrypt advertised has a risky future with all the new
protections planed for smartcard and CAM). Is this can be done directly in
the APB7202 chip or all data has first to be retrieved by the kernel before
being send back to the CI trough sec0?

  * Create the dvr0 and demux0 devices for the sec0 output

- Having the tuner#2 working without the CAM, with its demux1, dvr1,
frontend1 devices

It may help to keep compatibility with existent DVB applications.
What do you think?

Best regards,
Sebastien.

 
 -Ralph

Sony CXD2099AR support

2011-02-28 Thread Issa Gorissen 
Hi,

I have read that this CI chip driver is in staging because some questions on
how to handle it are still not answered.

I volunteer to handle this one. I'm a regular java developer, but I'm willing
to put effort in learning linux drivers writing.

So Ralph, can you give me some pointers on where the discussion should resume
?

Do we put people of Mythtv and VDR in the discussion ? I guess so.

I don't see anything related to MTD in the DVB CSA documents. I guess this
should be left out of the driver.

Thx,

 Follow up on the trouble with Digital Devices DuoFlex S2, CI, SMIT Viaccess
 CAM and Bis.tv card.
 
 The whole combination works under Windows 7 with Media Center. I have been
 able to watch and change channels I'm entitled to in the Bis.TV package.
Only
 condition was to disable CI for tuner no 2. If the CI is activated for tuner
1
 and tuner 2, Media Center will not be able to change the channels.
 
 Anything I can do to make progress for this issue under linux ?
 
 
 Thx
